My dmgr(v6.1.0.17) will fail to start up if I were to start it without having my other computer(which is a part of the cluster), turned on. This is just for testing purposes so I had the dmgr installed on my notebook, with some other nodes on a different computer. The dmgr started up fine as soon as I boot up the other computer. Is this normal? Is there a workaround for this issue?

I've googled based on the error, found this [url]http://www-01.ibm.com/support/docview.wss?uid=swg1PK22694[/url], but that's for v6.0.x.

Re: HMGR0024W: An error was encountered while looking up the IPaddress.

Hello,

Managed to solve the problem by changing the Core Group settings - configure the Transport Type from 'DCS' to 'Unicast'.
